PaveSaver™ is a new generation of non-shrink epoxy-based elastomeric concrete featuring an ideal balance for both flexibility and strength. This unique combination provides an excellent long-term patching solution for repairing cracks and spalls on airfield, bridge decks, bridge expansion joint headers, and highway pavements.

PaveSaver™ Advantages

General

PaveSaver™ Polymeric Concrete Patch

1. High-load bearing capacity – Handles the weight of C-4s, 747s and heavy truck traffic.

2. Outstanding anti-spalling properties – PaveSaver™ is a long-term solution for high-performance pavement repairs.

3. Impact resistant – Under bitterly cold conditions, PaveSaver™ withstands heavy impact and resists shattering, unlike conventional concrete and imitation epoxy-based materials.

4. High compressive strength – PaveSaver™ can handle heavy psi pressure before deflecting.

5. Chemical resistant – PaveSaver™ resists commonly used chemicals such as ASTM Oil #1, ASTM Fuel A, Ethylene Glycol, Freon, Isopropyl Alcohol, JP-4 Jet Fuel, Silicone Grease, Sodium Chloride, Mineral Oil, Trisodium Phosphate and Potassium Acetate.

6. Easy to install – PaveSaver™ is semi self-leveling and has a rapid cure time. This minimizes expensive downtime and allows for the return of traffic often within 3 hours after final pour. It also protects work crews by minimizing exposure to heavy traffic. PaveSaver™ can be mixed in 70-quart multi-purpose buckets or in approved mortar mixers for high volume applications.

7. Flexibility – Cement, phosphate, and most other high early strength repair materials prematurely fail because they are rigid. Rigid repair materials installed in rigid pavement require that the materials have similar coefficient of expansion. Most do not and, as a result, destroy the patch and the surrounding concrete. PaveSaver™ utilizes a unique epoxy chemistry to provide a flexible patch that will deflect as surrounding concrete expands and contracts.

Packaging

Saw cut, chip, or mill area to be repaired, leaving only sound concrete. Carefully sandblast all areas which will be in contact with PaveSaver™. The repair area must be clean and dry and the substrate must be a minimum temperature of 40°F (5°C). The minimum age of hardened concrete for bonding should be 5-7 days.

Area Preparation

Mixing and PlacingStep 1Pour premeasured amounts of Part A and B liquids into the mixing bucket. Using a spatula, thoroughly scrape the sides and bottoms of the cans to get as much of the resin liquids as reasonably possible into the mixing bucket. Failure to do this could result in irregular color or a dry mix.Step 2Place Jiffy type mixer at the bottom of the bucket to avoid introducing air and thoroughly mix on low-speed (300 rpm) for 3 minutes. The material should have a uniform consistency with no visual color streaks.

Step 3Slowly add component C (aggregate) to the mixed liquid components.Step 4 Mix thoroughly until all aggregate is wetted out.

Step 5Immediately place mortar. Thoroughly compact and trowel finish the surface.Step 6For repairs along existing joints, the joints should be maintained by the use of forming materials or saw cutting method.

Materials/Equipment Jiffy style mixing attachment, heavy-duty drill, clean and dry mixing bucket, spatula, bucket scrapers, and finishing trowels. A D.S. Brown approved mortar mixer may be used for large projects.

Storage ConditionsStore at 40°- 95°F (5°- 35°C). For best results, condition material to 65°- 85°F (18°- 29°C) before using.
